Android Question detect dB

[gerredtor]

Hello, ich would like run a recording in the Background which measures the dB (decibel). Furthermore it should trigger an Event if the the dB reaches a certain level.

You can use AudioStreamer to capture audio. You will need to analyze the raw PCM data and find the level.
